Introduction:  Measuring Eyesight

Many people don’t realize the simplicity of all the measurements done specifically to correct myopia at the optometrist.

At the optometrist shop there are many tools, everything is done quickly and usually without explanation of the very basic principles of how glasses prescriptions are determined for your eyes.

If you knew how to do it yourself, they would be letting you onto the slippery slope of self discovery – and ultimately, to question the entire practice of using glasses to cover up the myopia symptom.

Understanding your eyes begins with understanding your myopia.  And for that, start with realizing one very simple fact about your glasses and the prescription numbers:

Diopters Are Just Inverse Meters.

What does that mean?

It means that you can very easily assess how much myopia you are dealing with.  You don’t need to go to the optometrist to find out if you need glasses, or stronger glasses.  You can accomplish the same thing, often more accurately, at home.  And now, with the new tools available here, you can do it without ever having to leave the house or buy any equipment at all.

Once you grasp the concept of diopters, you’ll be tempted to experiment.  I encourage you to measure your eyesight in the morning, and after a long day of close-up work.  Measure in good outdoor ambient lighting, and in an almost dark room.  Compare your findings.  Begin to realize that there is so much more to eyesight health than that optometrist visit would suggest.

As you begin to see how much your activities and environment affect your day to day vision, you’ll start to realize another important fact:

You Can Measure Your Eyesight More Accurately On Your Own.

In the blog you find me occasional talking about common optometrist tools, like the autorefractor.   We talk a whole lot about overprescription, and the fallacy of the establishment’s single prescription theorem.  All this starts to make sense as you begin to take measurements, keep a bit of a log, and begin to the see the full picture that the optometrist has no interest in showing you.

Of course this is a large topic – which we explore at length in my member only therapy access.

In the meantime, let’s get to the tools you can use to measure your eyesight:


The charts and rules, along with lots more tools and guides are now available in the measuring course.  See the courses link at the top of the page for more.
